Luke 2:5

3And all went to be taxed, every one into his own city.

4And Joseph also went up from Galilee, out of the city of Nazareth, into Judaea, unto the city of David, which is called Bethlehem; (because he was of the house and lineage of David:)

5To be taxed with Mary his espoused wife, being great with child.

6And so it was, that, while they were there, the days were accomplished that she should be delivered.

7And she brought forth her firstborn son, and wrapped him in swaddling clothes, and laid him in a manger; because there was no room for them in the inn.
